Pubic lice or Phthirus pubis, also called crabs, are tiny insects found in your genital area. They are a different type of insect than head lice and body lice. Measuring less than 1/8 inch (3 millimeters), pubic lice received their nickname because their bodies resemble sea crabs.
The most common way to acquire pubic lice is through sexual intercourse. In children, pubic lice may be found in their eyebrows or eyelashes and can be a sign of sexual abuse. However, children can sometimes catch pubic lice from heavily infested parents simply by sharing a communal bed.
Pubic lice feed on your blood and their bites can cause severe itching. Typically, pubic lice can be treated at home. Treatment includes applying over-the-counter creams and lotions that kill the parasites and their eggs. If someone in the house has them, it’s important to take precautions so that they don’t spread.
